[0001] This invention generally relates to a lighting system and/or a wide-area graphic
display system, and more particularly, pertains to a decorative lighting system for
use in a bowling center.
[0002] Decorative lighting systems have been used in bowling centers in which light ropes
are run along the bowling lane dividers so as to extend in parallel down the length
of the bowling lanes. These light ropes include a plurality of spaced apart light
bulbs provided along the length of the light rope. In general, such light ropes are
only capable of providing a few light patterns. Aside from merely being all on or
all off, the light bulbs in a light rope may be flashed on and off together, or may
be turned on and off in a marquee style whereby every third or fourth light in the
light rope is flashed on and off in parallel in a runing sequence. Furthermore, the
color of light emitted from the light rope from any one light bulb is fixed thereby
significantly limiting the capabilities of such decorative lighting.
[0003] Although such light ropes are well-suited for running down the sides of each lane
due to their linear nature, the limited capability of these light ropes does not allow
for all such light ropes in the bowling center to be synchronized in any manner or
otherwise produce any light show across the entire bowling center.
[0004] The present invention aims to alleviate the disadvantages and problems of the prior
art.

of addressable light strings each including a plurality of independently controllable
light modules that emit light in response to an activation signal uniquely associated
with each light module; and a control circuit coupled to said addressable light strings

[0054] In another aspect of the present invention there is provided a lighting system that
allows independent control of each lighting element of the system.
[0055] Another aspect of the present invention provides a lighting system m which the color
of each lighting element in the system may be independently selected and dynamically

[0056] Yet another aspect of the present invention provides a lighting system in which each

[0057] Still another aspect of the present invention provides a lighting system in which
each of the lighting elements is independently addressable and the lighting elements
are arranged in a plurality of linear strings so as to be well-suited for implementation
along the division caps of a bowling center.
[0058] In accordance with and to achieve these and other aspects and advantages, a lighting

system may also include an audio interface for coupling to an output of an audio device,
such as the bowling center's audio system. With such an audio interface, the controller

the light modules in response to the audio signal received through the audio interface.
In this manner, the lighting system may be synchronized with the music played throughout
the bowling center.
[0060] The invention extends to and envisages of any one of the above aspects taken alone,
a combination thereof, or simply any combination of their common features and the
optional features thereof.
[0061] These and other features, advantages, and objects of the present invention will be
further understood and appreciated by those skilled in the art by reference to the
following specification, claims, and appended drawings.

[0063] Fig. 1 shows an example of a lighting system 100 constructed in accordance with an
embodiment of the present invention. In general, lighting system 100 includes a central
controller 110, a plurality of address modules 120
1 through 120
N coupled to central controller 110 by a data cable 115, and a plurality of light strings
130
1 through 130
N, each associated with and coupled to one of address modules 120
1 through 120
N. Each light string 130
n includes a plurality of light modules 140
n,1 through 140
n,M coupled together in a linear fashion.
[0064] As will be explained in more detail below, central controller 110 may be coupled
to an external device or system 150, such as the bowling center's bowling scoring
system and/or may be coupled to an audio system 160, such as a bowling center's music
system.
[0065] Fig. 2 shows an example of how lighting system 100 may be implemented in a bowling
center. As shown in Fig. 2, a bowling center typically includes a plurality of parallel
lane surfaces 12. Such lane surfaces are typically grouped into pairs so as to share
a common ball return. Between the lanes associated with different lane pairs is a
division member 16. The preferred structure for a division capping assembly 20 that
is mounted on division member 16 is described below with reference to Figs. 3 through
5. It is within the division capping assemblies 20 that the light strings 30 are preferably
run. As further explained below, the division capping assemblies have a transparent
cover to allow light projecting from the light modules 140 to be viewed by the bowlers
and spectators.
[0066] As described above, each light string 130 is coupled to an address module 120
1 through 120
8, which are coupled to a central controller 110 via a data cable 115. The address
modules may be mounted within the division capping assemblies, the bowling scoring
consoles or anywhere else in proximity to one end of each light string. Conceivably,
the address modules may be mounted behind the masking units and/or pinsetters. Central
controller 110 may be disposed at the front desk of the bowling center, in a front
office, or anywhere else in the bowling center.
[0067] As shown in Figs. 3-5, each bowling lane 12 has a lane surface 10 lying between a
pair of lane-straddling gutters such that one gutter 14 of each lane 12 is immediately
adjacent the gutter of the next lane, with a division member 16 therebetween. On the
opposite side of each of the two lanes 12 depicted in Fig. 3 is the second gutter
(not shown) which is adjacent the ball return, in conventional manner.
[0068] Preferably the gutter elements 14 have an upstanding support leg 14a adjacent lane
12 and a support flange 14b on the opposite edge of the gutter resting on division
member 16. Flange 14b is interengaged with the lower member 22 of assembly 20, with
both member 22 and the gutters being secured to division member 16 by threaded fasteners
such as screws 30.
[0069] Lower member 22 is preferably an elongated extrusion element which runs the length
of the bowling lane, preferably in segments thereof. This lower member has a lower,
i.e., bottom, wall 22a, a pair of side walls 22b which extend integrally up from lower
wall 22a, and a pair of upper flanges 22c which extend integrally from the upper ends
of walls 22b generally toward each other but defining an open elongated channel 24
therebetween that serves as a convenient pathway for stringing the light strings 130.
The side walls and flanges may be one continuous curve instead of extending upwardly
and then inwardly. Protruding from the bottom of lower wall 22a are a pair of protrusion
ribs 22d for engaging recess grooves in the respective adjacent edge portions of gutters
14. Alternatively, the recess grooves can be in member 22 and the protrusion ribs
in flanges 22c.
[0070] The upper cap member 26 of assembly 20 comprises an upper wall 26a and a pair of
spaced legs 26b depending downwardly from upper wall 26a. The cap may be in segments
for easy handling and assembly. The legs 26b are spaced apart an amount about equal
to the width of space 24, and have laterally outwardly offset detents 26c extending
in opposite directions. The lower portions of these detents are sloped upwardly outwardly
for engagement with flanges 22c whereby downward force applied to cap member 26 causes
legs 26b to be shifted inwardly by flanges 22c against the inherent bias of the legs
until detents 26c engage beneath the bottom surfaces of flanges 22c. The presently
preferred polymer for the base member and the cap member is rigid polyvinylchloride
(PVC) but could be a polyester or any other suitable polymer. The outer edges of upper
wall 26a of cap 26 preferably have downwardly outwardly sloped tapered flanges 26d
which are resiliently upwardly deformable slightly as detents 26c snap beneath flanges
22c for tight securement. Cap member 26 is translucent or transparent such that output
from spaced lights located within the hollow assembly 20 will be viewable along the
length of the bowling lanes to provide highly colorful effects. Conceivably, the lower
member can also be translucent or transparent.
[0071] By using the above-described construction for the division capping assemblies 20,
cap 26 may be readily removed and re-attached to allow the light strings to be easily
strung along the length of the lane. Further, this division capping construction allows
for quick access and replacement of the lighting modules. Although the light strings
are described as being run within the division capping assemblies, the light strings
may also be run on or within the ball return capping assemblies.
[0072] As shown in Fig. 6, each light module 140 may be formed on a circuit board 30 and
mounted in a housing 40. Preferably, light module 140 includes a multi-color lighting
device including three light emitting diodes (LEDs) or a single LED with multiple
(3) colors as light sources. More preferably, these LEDs include a red LED 32, a green
LED 34, and a blue LED 36. By providing red, green, and blue LEDs, which are the primary
additive colors, each light module 140 may be controlled to emit not only one of the
red, green, or blue colors, but also to emit white, cyan, yellow, or magenta when
combinations of LEDs 32, 34, and 36 are illuminated.
[0073] To project the light from LEDs 32, 34, and 36, a portion 44 of the upper surface
of housing 40 is sloped upward to define an opening 46 through which the light is
projected. An inner surface of portion 44 preferably has a reflector 48 disposed thereon.
In this manner, light modules 140 may be disposed within channel 24 so as to project
the light back toward the approach area of the bowling lanes so as to appear more
bright to the bowlers and spectators. Housing 40 may be provided with an aperture
42 defining a connection port 35 from which connector pins 38 extend from circuit
board 30. Connector pins 38 are provided to allow coupling to a plug 50 of a wiring
cable 125 which extends from the opposite end of the next light module 140. It will
be appreciated that port 35 may be configured as a female port having receptacles
rather than a male port having pins 38.
[0074] Light module housing 40 may also include a similar port at its opposite end for coupling
to a wiring cable 125 of another light module 140 or may have the cable 125 more permanently
mounted thereto. With a port 35 at one end and a cable 125 with a plug 50 provided
at an opposite end, such light modules may be serially coupled together to form a
light string. It will be appreciated, however, that wiring cables 125 may be permanently
mounted to both ends of light module 140 so as to have a plurality of such light modules
140 permanently strung together. However, such a permanent mounting may be less desirable
if it should become necessary to replace any one light module within the light string.
[0075] Having described the physical components of this preferred embodiment of a lighting
system in accordance with the present invention, the electrical and functional aspects
of the inventive lighting system are described below with reference to Figs. 7 through
9. As shown in Fig. 7, each address module 120 includes a pair of cable connectors
111 and 112 for coupling into and forming a part of data cable 115. It will be appreciated
by those skilled in the art that connectors 111 and/or 112 may be mounted within an
address module housing or be mounted at the end of a cable extension so as to mate
with the connector of an upstream or downstream address module. As shown in Fig. 7,
cable 115 includes power supply lines 113 for providing power to each address module
system, ground lines 114, and an earth ground line 116. Further, cable 115 includes
two lines 117 upon which is transmitted a differentiated load signal, a second pair
of lines 118 upon which is transmitted a differentiated data stream, and a third pair
of lines 119 upon which is transmitted a differentiated clock signal. The load signal,
data stream, and clock signal are described in more detail below.
[0076] Address modules 120 also include a load line interface 122 coupled to line pair 117,
a data line interface 123 coupled to line pair 118, and a clock line interface 124
coupled to line pair 119. Load, data, and clock line interfaces 122 through 124 receive
the differentiated signals on the respective line pairs and generate a load signal,
a data stream signal, and a clock signal, respectively. Preferably, these interfaces
utilize an optical coupling so as to reduce the current drawn from bus 115.
[0077] Address modules 120 further include a first power converter 121a and a second power
converter 121b. First power converter 121a is coupled to the ground and power lines
of cable 115 for supplying power to those portions of interfaces 122, 123, and 124
that are coupled to cable 115. Second power converter 121b is provided to convert
power received from an external power supply and supply power to light strings 130
and to those portions of interfaces 122, 123, and 124 that are optically isolated
from cable 115. By using two power converters, the light strings may be isolated from
cable 115.
[0078] The data stream signal as output from data line interface 123 is supplied to an 8-bit
shift register 126. As the data stream signal is received by shift register 126, it
is shifted through shift register 126 in response to the clock signal output from
clock line interface 124. As data is shifted through register 126, it is passed along
on line 138 of wiring cable 125 to the first light module 140
1 of the light string 130. This data is received by a 3-bit shift register 146, which
shifts this data therethrough in response to the same clock signal to which 8-bit
shift register 126 responds. As the data is shifted through 3-bit shift register 146,
it is passed downstream to the 3-bit shift register of the next light module. When
twenty light modules 140 are provided in a light string, the serially-connected 3-bit
shift registers of each of the light modules 140 and the 8-bit shift register 126
of the associated address module 120, effectively operate as a 68-bit shift register.
As such, new data may be loaded into the shift registers every 68 clock pulses. Thus,
the first 60 bits of a data signal transmitted on line pair 118 will correspond to
twenty 3-bit data signals used as activation signals to control the LEDs 32, 34, and
36 in each light module. The last 8 bits of the data stream will correspond to an
address that is stored in 8-bit shift register 126.
[0079] As shown in Fig. 8, for every 68-bit data signal that is clocked through 8-bit shift
register 126 and the twenty 3-bit shift registers 146 of a light string, a load signal
is transmitted on line pair 117. This load signal is supplied by load line interface
122 to an AND gate 134. The other input of AND gate 134 is coupled to the output of
an address comparator 128 that compares the 8 bits that are stored in 8-bit shift
register 126 at that time with an 8-bit address uniquely associated with address module
120. If the address in 8-bit shift register 126 corresponds to the unique address
of the address module 120, address comparator 128 supplies a high logic level to AND
gate 134 thereby enabling AND gate 134 to respond to the load signal by outputting
the load signal on line 136 of wiring cable 125 to a latch circuit 148 of each light
module 140. Latch circuit 148 is coupled between the 3-bit output of the 3-bit shift
register 146 and three switching elements, such as transistors 152 through 156, which
selectively activate a respective LED 32 through 36. Latch circuit 148 maintains LEDs
32 through 36 in their current illuminated state until such time that a load signal
is received on line 136. When a load signal is received on line 136, latch circuit
148 applies the 3-bit output from 3-bit shift register 146 to switches 152, 154, and
156, respectively, to thereby change or maintain the illuminated states of LEDs 32,
34, and 36 in correspondence with the 3 bits of data that are stored in 3-bit shift
register 146 at the time that the load signal was received on line 136.
[0080] If, on the other hand, the address comparator 128 determines that the 8 bits of data
stored in 8-bit shift register 126 do not correspond to the unique 8-bit address of
address module 120, address comparator 128 outputs a low logic level signal to AND
gate 134 thereby preventing AND gate 134 from transmitting the load signal on line
136 when it is received from load line interface 122. Thus, unless the last 8 bits
of the 68-bit data stream correspond to the unique address of the address module,
the light string will not respond to the previously-transmitted 60 bits of data that
have been shifted into the 3-bit shift registers 146 of light modules 140
1 through 140
m. As shown in Fig. 7, the unique address for the address modules may be selected using
a plurality of DIP switches 132. Preferably, address comparator 128 also compares
the 8-bit address stored in shift register 126 with a global address that is shared
in common with all the address modules 120 of the lighting system. In this manner,
central controller 110 may enable all the light strings to respond to a common data
signal transmitted to all the light strings using one 68-bit data stream.
[0081] With the construction shown in Fig. 7, each LED of each light module of each light
string may be independently controlled by central controller 110. Thus, controller
110 may control when, and for how long, each light module emits light. Controller
110 may also control the color of the light that is emitted from each light module.
With such flexibility, central controller 110 can create a virtually unlimited number
of lighting patterns on the light strings.
[0082] Although the lighting system has been described as utilizing 20 light modules per
string and utilizing 8 bits of the data stream for an address, it will be appreciated
by those skilled in the art that the number of light modules per string may be arbitrarily
increased or decreased and that the number of bits per address may be varied as a
function of the number of address modules/light strings that are provided. Further,
given that the address modules 120 are daisy-chained together, an arbitrary number
of such address modules may be connected into the system. Further, certain concepts
embodied in the inventive lighting system may be implemented using more or less than
three LEDs per module.
[0083] Having described the manner by which the address modules and light strings respond
to the clock, data, and load signals transmitted by central controller 110, the manner
in which central controller 110 selects which data to supply is described below with
reference to Fig. 9.
[0084] Central controller 110 preferably includes a central processing unit (CPU) 200, a
code memory 202, a data memory 204, a memory I/O decode logic circuit 206, a first
output port (port 0) 208, a second output port (port 1) 210, an input port 212, a
multi-point data cable interface 214, a front panel switch interface 216, configuration
dip switches 218, a front panel display interface 220, a watchdog timer 222, and an
EEPROM 224. CPU or processor 200 controls all the functions and operations of central
controller 110. In general, processor 200 executes operating instructions stored in
code memory 202 as received over a data bus 225 connected therebetween. Code memory
202 is preferably in the form of an EPROM. Code memory 202 also preferably stores
numerous preprogrammed display patterns that may be read therefrom in any sequence
in accordance with address signals received from processor 200 via an address bus
227. When a preprogrammed display pattern is read from code memory 202, it is transmitted
over data bus 225 to first output port 208. First output port 208 creates the data
stream that is transmitted to each of the addressable light strings via multi-point
data cable interface 214 and data cable 115. First output port 208 also transmits
a periodic strobe signal to watchdog timer 222. Watchdog timer 222 is provided to
transmit a reset signal to processor 200 whenever a strobe signal is not received
from first output port 208 within a predetermined time interval. In this manner, central
controller 110 will not become locked up.
[0085] Memory I/O decode logic circuit 206 is provided to map all memory and I/O address
locations. Circuit 206 is coupled to receive address signals from processor 200 or
data memory 204 via address bus 227 and to receive read and write commands from processor
200. In response to information received at its inputs, decode logic circuit 206 transmits
control signals to first and second output ports 208 and 210 that causes these output
ports to output the data received on data bus 225 through their respective output
lines. Further, decode logic circuit 206 may respond by sending a read signal to input
port 212 to cause it to read inputs from front panel switch interface 216 or configuration
dip switches 218 and to transmit these inputs on data bus 225 so that they may be
received by processor 200. As will be explained further below, decode logic circuit
206 further transmits read and write signals to an analog-to-digital (A/D) converter
240 of an audio interface 228 to cause it to send or receive data on data bus 225.
[0086] As shown in Fig. 9, central controller 110 may further include an external device
interface 226 to which an external device, such as the bowling center's bowling scoring
system, may be connected. Preferably, interface 210 is a standard RS-232 Serial Port
and processor 200 includes a UART so as to enable any conventional personal computer
(PC) or server to be connected to central controller 110. By connecting the bowling
scoring system to external device interface 226, processor 200 may receive prompts
from the scoring system that identify a particular lane or lane pair, and an event
that occurred at the identified lane. For example, the bowling scoring system may
inform central controller 110 that a strike has been rolled on lane 4. In such an
event, central controller 110 could respond by transmitting data streams including
the addresses for the two address modules on the adjacent borders of lane 4 so as
to create a specific light show with respect to that lane. Thus, the light bordering
that lane may be used to create a light show in synchronism with the exciter graphics
shown on the scoring system displays.
[0087] Central controller 110 may further include an audio interface 228 which enables central
controller 110 to interface with an audio device or system, such as the bowling center's
audio system. Audio interface 228 preferably includes RCA input jacks 230 into which
an audio line level signal may be received from the audio device or system. The line
level signal is then split and applied to a high pass filter 232, a band pass filter
234, and a low pass filter 236. Filters 232, 234, and 236 are provided to separate
the input audio signal into its treble, midrange, and bass frequency components. Although
separation of the treble, midrange, and bass frequencies is disclosed, the audio signal
could be separated into any number of different frequency bands. The outputs of each
of these filters are applied to an analog switch 238, which is responsive to band
select signals supplied from processor 200 to select one or more of the separated
frequency components to supply to the input of A/D converter 240. A/D converter 240
converts the amplitude of the selected frequency component of the input audio signal
into an 8-bit digital value. This 8-bit digital value may be output on data bus 225
and received by processor 200 when it receives a write-enable signal from decode logic
circuit 206.
[0088] Through the operation of a switch on front panel switch interface 216 or the operation
of a configuration dip switch 218, processor 200 may be set in a music mode whereby
it instructs decode logic circuit 206 to enable A/D converter 240 to output a digital
value representing the amplitude of a received audio signal on data bus 225. Processor
200 receives this digitized amplitude level and responds by selecting a light display
data pattern that may vary in some respect as a function of the digitized amplitude
level of the input audio signal. Further, as noted above, processor 200 may select
either the treble, midrange, or base frequency component of the input audio so as
to change the lighting patterns in response to either the amplitude of the base, midrange,
or treble component levels. Thus, processor 200 may control the light patterns generated
by the light strings in synchronism with the music played on the bowling center's
audio system. Processor 200 may be configured so as to generate a lighting pattern
in which the light strings are illuminated to simulate a power meter of, for example,
a graphic equalizer, or may control the different LEDs of each light module so as
to change color in response to the component amplitude levels of the input audio signal.
The specific manner by which processor 200 responds to the input audio signal may
be set by an operator through the actuation of a switch on front panel switch interface
216 or the operation of a dip switch 218. It will be appreciated by those skilled
in the art that processor 200 may be programmed to respond to the input audio signal
level to create virtually any sequence of lighting patterns in response to the characteristics
of the input audio signal. It should further be noted that processor 200 may dynamically
vary the bid selection signal applied to analog switch 238 so as to modulate the different
lights in each module in response to different frequency components of the input audio
signal.
[0089] Front panel display interface 220 is preferably coupled to a display that is mounted
in a location that may be viewed by the operator. By providing a display device, information,
such as the operating mode, may be displayed to an operator. The information to be
displayed on the display device may be transmitted from one of the memories or processor
200 over data bus 225 to output port 210, which, in turn, transmits the display information
to front panel display interface 220 when a write-enable signal is received from decode
logic circuit 206. The display device may further be controlled directly by processor
200, which is directly coupled to front panel display interface 220.
[0090] Data memory 204 is provided as a "scratch pad" memory for processor 200 and for storage
of display patterns that may be downloaded via external device interface 226 from
an external device. In this manner, the various lighting patterns that may be displayed
by the lighting system may be varied at any time after installation of the system
in a bowling center. EEPROM 224 is a nonvolatile memory used to store semi-permanent
system configuration data that is utilized by processor 200.
[0091] According to an alternative embodiment shown in Fig. 10, the number of colors of
light that may be emitted from each light module may be significantly increased by
providing a variable gain amplifier 300 for each LED 32, 34, and 36, and by replacing
the 3-bit shift registers in each light module 140 with 9-bit shift registers 302
so as to enable a 3-bit intensity level to be applied to each variable gain amplifier
300. In this manner, the intensity of the light emitted from each LED may be selectively
controlled thereby enabling the saturation and hue of the light emitted from each
light module to be controlled by the central controller.
[0092] Although the present invention has been described as being implemented in a bowling
center, the light system could be employed in other locations or entertainment facilities.
For example, the light modules could be embedded in a dance floor or the floor in
a roller skating rink. Further, it should be noted that the light strings need not
be arranged in parallel spaced lines, but instead may be laid out in a more serpentine
fashion to form various shapes. Further, the light strings may be intertwined and
intersect so long as the surface area on which they are mounted does not require that
each light string is disposed in parallel spaced apart fashion as would be desired
when mounting in the division caps of a bowling center. In this regard, it should
also be noted that light strings may alternatively or additionally be mounted to the
walls, masking unit, or ceiling of a bowling center. Such additional light strings
could be controlled in synchronism by the same central controller used to control
the lights in the division caps.
[0093] Given the flexibility provided by lighting systems which are embodiments of the present
invention, such lighting systems may be used to create graphic displays. For example,
by arranging the light strings and light modules into a plurality of rows and columns
(as would typically be the case when they are mounted in the division caps of a bowling
center), a dynamic graphic display may be created through appropriate transmission
of the data signals to the light modules. For example, the resulting two-dimensional
array of light modules may be selectively illuminated in a dynamic fashion to display
a game of PONG whereby the two outer light strings of the matrix are used to illuminate
moving paddles and the remaining inner light strings may be used to create the illusion
of a ball moving back and forth between the paddles. Moreover, given the ability of
the lighting system to change the color of the light emitted from each light module,
each light module may be viewed as a pixel of a wide-area graphic display. Such a
wide-area graphic display may be used in virtually any location including placement
on building exteriors and on billboards.
